Class ForwardingIOStatisticsStore

java.lang.Object

org.apache.hadoop.fs.s3a.statistics.impl.ForwardingIOStatisticsStore

All Implemented Interfaces:

org.apache.hadoop.fs.statistics.DurationTrackerFactory, org.apache.hadoop.fs.statistics.impl.IOStatisticsStore, org.apache.hadoop.fs.statistics.IOStatistics, org.apache.hadoop.fs.statistics.IOStatisticsAggregator

public class ForwardingIOStatisticsStore
extends Object
implements org.apache.hadoop.fs.statistics.impl.IOStatisticsStore

This may seem odd having an IOStatisticsStore which does nothing but forward to a wrapped store, but it's designed to assist in subclassing of selective methods, such as those to increment counters, get durations etc.
